Garage Door Opener
My GDO seemed to be working fine, however, at times the sensors would be out of alignment. I would simply adjust the sensor and down the door would go. This past weekend, I was cleaning the garage and when I tried to put the door down, it would go a little bit and then back up and the light would blink 10 or 11 times. The lights on the sensors are not on but the wires seem to be properly connected. How do I know if it is the wiring, the sensors, or the motor?
